Evolution Aquas quartz 30w / 55w replacement sleeves are designed specifically to replace the existing quartz sleeves in the Evolution Aqua EVO30 and EVO55 clarifier range. These quartz sleeves help protect the bulb from air and water flow, breakage, leakage, temperature fluctuations, and environmental hazards. They should be replaced once a year as algae and dirt can cloud the tube making the UV bulb less effective. It's also advisable to replace the rubber O-rings for your quartz yearly as these can go brittle and crack. For Use With: Evolution Aqua EVO30 and EVO55 models Length: 87cm Internal Diameter: 2.6cm
